Hi, here in this given problem first of all we draw a cartesian plane.
00:07
This is the cartesian plane, having x -axis horizontal, y -x is vertical.
00:15
One of the charge is put at the negative x -axis, which is at a distance of 9 cm from the origin.
00:25
Suppose the charge is q1.
00:27
This charge q1, that is minus 3 .0, nanoculum.
00:32
And this distance oa that is 9 cm, then another charge is put at the positive x -axis at a distance of 16 centimeter and the charge q2 is put over here and this q2 is equal to plus 4 .0 nanoculum and the distance ob 16 centimeter.
00:58
Now this is the observation point at a distance y.
01:03
So, suppose electric potential that is 0 at a point c, which is distant y from origin on the y axis...
